issue with network connection when connecting to another pc on LAN via network drive

Hello
For some days now am having an issue with my network connection, as when I connect to a shared folder on another pc via Map network drive, when I copy and paste a file from the shared folder to my own harddrive, my sent packets values are boosted quickly, and finally to such an extent that it looks like a 'flooding' has occurred, and am unable to connect either to that pc again or on the internet, thus leaving me no choice but to restart my machine and try copy the file again.
Anyone can help me with this? Why this happens and how to solve it if possible?

Download Ethereal to see where the packets are going, you may have a trojan that's phoning home when connecting and causing the flood of packets. If that's the case, get MalwareBytes and do a scan in safe mode.
